http://forums.tdiclub.com/showthread.php?t=94046&highlight=TCM+programYou recode the soft coding of the TCM. It is in DSP mode by default. DSP (Dynamic Shift Program) switches automatically between Sport and Economy, based on the driver's behavior... this is sometimes known as 'fuzzy logic'. Problem is, Germans don't really know how an automatic is supposed to work anyways, and when the DSP is enabled, the shift mapping on the 01M often gets a little disconnected feeling and erratic. Basically, DSP IMHO adds insult to injury on a transmission that is already by design predisposed to being goofy. By setting it in either Sport or Economy, based on your specific taste, the TCM will make the shift mapping behave more predictably. Otherwise, it is almost a necessity to clear the TCM's shift tables at every service to reset its fuzzy logic, or they just start to shift strange.
To me, if you drive a lot of highway and not much stop and go, putting the TCM in Economy mode works fine. If you do a lot of city, or a mixture of either, Sport mode works better. And it is not just the 01M that is like this, the 01L and 01V is like this as well. My Passat has had its TCM in Sport mode since about 1 hour after I bought it 6.5 years ago.
Is this the correct process to lock the TCM into sport or economy ?
The way the thread sounds it should do the trick -- I think I will try this as mine shifts oddly at times.
